It would seem that the low posts have an even bigger advantage in this form of scoring, although I am saying that off the top of my head and a simulation program could prove me wrong. Regardless, I don't see why at least a few games per night couldn't be played this way. However, I thought I read somewhere that the reason Spectacular 7 was invented was to facilitate trifecta wagering since all trifecta combos were not possible under the old scoring system.
